Hathway / Gujarat Telelink [GTPL] — Complain for refund due to not install the broadband connection

I bought a GTPL optical fiber connection on the 28th of November and paid Rs.8899 for 150 mbps speed with optical fiber.
Till date after 17 days GTPL connection has not been installed on my requested address at C902.
Mr. Satish Parmar Mob GTPL sales executive [protected] & Rr. Rahul Ponikar +[protected] had visited on 28th November 2021 and after his assurance that 150 mbps speed connection will install and work in 2 to 3 days I have paid Rs.8899 in advance to install connection at my Residence C902.

Now after 17 days GTPL is unable to install a high speed connection for which I have paid money in advance. I would like to register complaints to GTPL and the customer forum for the same.
GTPL should return all my money with. I even lost 17 days o[censored]nused data time for this period. I had to pay a big charge to another service provider for my work with the internet.

I look forward to your reply and a resolution to my problem. I will wait until 24 November before seeking help from a consumer protection agency or other assistance. Please contact me at the above address or by phone.
